Jennifer needs to use a ladder to clean a second floor window on a building. If the window is 13ft above the ground and the base of the ladder is 4ft from the building, which equation below can be used to determine the length of the Ladder needed to reach the window

A 42 + 139 = 2

В

4² + x² = 13²

С

132_4? = ?

D

132P = 42

Step-by-step explanation:

we have a right triangle,

to find out the hypotenuse, h

H^2=13^2+4^2

H^2=169+8=177

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
